Primitive never type for code paths that do not return normally.
# =============================================================================
# numquam — Primitive never type for code paths that do not return normally.
# =============================================================================
#
# What this teaches:
# • Diverging functions — `numquam` marks functions like `mori` that never return to the caller.
# • Type-system bottom — `numquam` is the bottom type, compatible with any return position.
#
# Common mistakes:
# • Using numquam for functions that might sometimes return normally — numquam is only for code paths that never return.
#
# See also: mori, exitus

# numquam — diverging return type

# GRAMMAR:
# returnType :← 'numquam'
#
# EXPECTED OUTPUT:
# Scalar stdout smoke (see body).
